Tuning My UNO idle speed flactuations

[UNO Fire 45]

Yesterday my uno was stopping when idling. My first tought was the ignition module as i recently renewed the spark plugs , ignitions leads. I clean the carburettor with a carburettor cleaner by unscrewing the jet and spraying inside ithe carb also i slightly bumped up the idle revs to keep it running but i can still see the engine going up and down when idling not smooth running. i dont know what is wrong as i replaced the igniton module with a new one magneti marelli and the problem still persists! my uno runs on unleaded petrol

please help!

Have you tried twisting the distributor? Could the timing be off?
Undo the top nut a little and twist it round until it runs better.

Some say to mark a line across the two so you can see how to put it back to how it was befor eyou started tinkering.
